FIELD: machine engineering.
SUBSTANCE: mechanical seal parts with the outer cylindrical surface comprises a female sealable shaft housing which are installed paired bushings lapped each other in the axial direction along the inclined end surfaces, the angle of inclination which is greater than the angle of friction, and preloaded against the sealing surface in opposite directions while deployed one pair relative to the other at an angle of 180°/n, where n - the number of pairs.
EFFECT: invention simplifies the design and improves the tightness of the mechanical seal.
